Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It only states the retrieval action without detailing permissions, rate limits, response format, or whether it's safe/read-only. This leaves critical behavioral traits unspecified for a tool in a complex environment.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
